7 Claims. 1

Thm invention relates to mounts, particularly to paper mounts, and has for its primary object to provide a machine for making display cards for jewelry and the like.

In the jewelry trade it i customar to mount earrings, lockets, etc., upon tissue covered cards to prevent the article of jewelry from tarnishing and also to enhance the appearance of the article as it is displayed. The enhancement of the article also depends upon a certain degree of looseness with which the tissue paper embraces the card. It has been customary heretofore, as far as applicant is aware, to manually loop the tissue paper around the card without securing one directly to the other. Thus in the prior practice the operator first placed one edge of tissue paper adjacent one edge of a cardboard, next continued the paper around the cardboard until it overlapped the first edge, and then applied adhesive, at several points between and adjacent the overlapped edges, leaving an unsecured margin along the last edge of the tissue paper. The combination of cardboard and tissue paper was finally cut according to the size of card required.

While the above practice is, in general, satisfactory, it is necessarily a slow process, being dependent upon the speed of the operator. At the same time, the unsecured margin of tissue paper tends to fray, fold over, and break the adhesive bond, thereby impairing the purpose for which the card was designed. Further, since the tissue paper is not secured to the cardboard, being merel looped therearound it has a tendenc to slide off.

It is, therefore, another object of the invention to overcome the above disadvantages by providing a machine that is adapted to afiix tissue paper to cardboard along a continuous strip and also to maintain the tissue paper on the cardboard with an optimal degree of looseness.

It is still another object of the invention to provide a machine for mechanically producing display cords, thereby substantially increasing production and lowering the cost thereof.

With the above objects in View, one embodiment of the invention discloses a machine comprising a feeding rack for holding cardboards in an upright position; a plurality of pairs of adhesive applying rollers disposed underneath the rack, so that each cardboard as it passes downwardly therebetween receives adhesive material in strips of predetermined width on both sides thereof; a shelf with an opening underneath the rollers for supporting tissue paper, the cardboard being adapted as it passes downwardly through said opening to engage the tissue paper and fold it against the sides thereof; and a pair of rollers for pressing the tissue paper against the cardboard, whereby one is adhesively secured to the other along the continuous strips, the unsecured intermediate portions of the tissue paper presenting a looseness of predetermined degree. The composite article is then dropped from the compression rollers into a container, after which displa cards of appropriate size are cut therefrom b severing the article midway along the adhesive strips and transversely in accordance with the desired length or" display card.

A more complete understanding of the invention will be obtained from the following description of a preferred embodiment thereof, taken in conjunction with the accompanying drawings in which:

Fig. 1 shows a vertical sectional view of the machine taken along line 1-! of Fig. 2;

Fig. 2 is a transverse sectional view taken along line 22 of Fig. l in which the essential elements of the machine are more clearly illustrated;

Fig. 3 is an enlarged sectional view of a portion of Fig. 2 showing the manner in which the tissue paper is picked up by the cardboard and secured thereto.

Fig. 4 is a perspective View of the completed composite article after having been acted upon by the apparatus of Figs. 1 and 2, the adhesive strips for securing the tissue paper to the cardboard being outlined in dotted lines; and

Fig. 5 is a perspective view of a display card cut out of the composite article shown in Fig. 4.

Referring now to the drawings, particularly to Figs. 1, 2 and 3, there is shown a pair of uprights ll] having at the upper portion thereof a hopper or feeder rack i2 for carrying a supply of cardboards M in a more or less upright position. The feeder rack l2 ma be of any suitable construction and, in the embodiment shown, preferably comprises a base member 16 having a slot 18 therein for passage therethrough of individual cardboards M; a pair of sides 20 that are adjustably mounted on the uprights ill by the usual thumb screw and nutcombination 22 in which plate elements 24 at the ends thereof are rigidly secured to the side 20; and rods 26, 2-8 constituting the back and front elements, respectively, thereof. As seen in Fig. 2, the front rods 28 are disposed just in front of the slot 18 to act as a stop, so that, as each cardboard l4 reaches the slot, it will automatically drop therethrough. To further insure this registration, the front of the base It is shown made of thicker material, a1;

though the base It may be of uniform thickness throughout with a backstop mounted adjacent the slot [8.

Underneath the feeder rack I2 is disposed an adhesive applicator 29 constituting a pair of shafts 30 suitably journalled in the uprights Ii! with a plurality of paired rollers 32 fixedly secured and longitudinally spaced at appropriate intervals. Each roller 32 is of predetermined width and is provided on its external periphery with a resilient material 3d, preferably of rubber. The spacing between the pairs of rollers 32 may be varied in any of a number of ways, such as by means of a set screw 33 mounted in the hub thereof and adapted to engage the peripheral surface of the shaft 39.

The shafts 38 and, in turn, the rollers 32 are disposed a predetermined distance apart, so as to leave a space therebetween sufficient to permit the cardboard i L to pass therethrough. Such space is preferably less than the thickness of the cardboard in order to permit a gripping effect by the rollers thereupon, whereby the cardboard will be driven downwardly, as viewed in Fig. 2. Each roller 32 is in contact engagement with a roller 35, which is fixedly disposed upon. a shaft 38, therollers 355 being adapted to apply adhesive mixture 39 from a container to to the rollers 32. The container to may be of any suitable configuration and is shown supported upon bars 42 affixed to the uprights ii] in any suitable manner. As seen in Fig. 1, there are four pairs of rollers 32 and 35 provided and these rollers are adapted to apply the adhesive mixture 39 to both sides of the cardboard Hi. The mixture 39 may comprise any suitable quality of adhesiveness, such as glue and the like, but it is preferable to use what is known as a white padding cement in order to prevent discoloration of the cardboard [4.

Below the adhesive applicator 72$ is shown a shelf 54 having a slot 36 midway between the right and left extremities thereof, as viewed in Fig. 2, the sides of the shelf 4t being rigidly secured to the uprights iii. The shelf d l is provided as a supporting element for a sheet of tissue paper 4! that is to be applied to the cardboard I 3 in a manner to be described hereinafter.

Directly under the shelf fill is shown a pair of rollers Q8 and E preferaoEy of steel, mounted upon shafts 52 and respe tively, that are suitably journalled in the uprights 5%. Roller is rotatable about a axis, while roller 58 is rotatable about a variable horizontal axis being urged against roll; 8 by a esilient compression spring ieniber 5 adjacent the ends thereof, which spring is secured at end to the upright if! and connected at the other end to a slidable element 56 disposed upon the shaft 52. It is thus seen that the rollers 559 function as com pression rollers a adapted to press the cardboard and tiles e paper together.

To maintain t1" ardboard id in vertical align ment during its p go through the device and also to enable the de\ ce to accommodate a pin rality of sizes of cardboards, a pair of aligning rods 53 are disposed below e slot 5 while a second pair of rods interposed between the adhesive a and the sh 1 id. The rods and 5a.: are each a ed, a pred rmined distance apart, so as to p board to freely pass therebetween, as become more apparent upon investiation of Figs. 2 and 3. Referring to these two figures, it will be noted that the slot I8, the respective spaces between the rollers 32, rods 60, and the slot 46, and the contact point between the compression rollers 48, 5B are in vertical alignment. It is, of course, understood that the rods 58 and 60 may be dispensed with in the event that cardboards of sufficient length are utilized. In other words, if the cardboard H! is of such length that one end of it is adapted to lie within slot l8 while the other end thereof is positioned in slot 46 of shelf 44, there is no need for any other alignment means. Further, to prevent the alignment rods 68 from removing some of the cement 39 from the cardboard during its passage therebetween, it is preferable to undercut these rods at the portions 62 indicated in Fig. 1.

The power supply for driving the device may be of any suitable type, such as an electric motor (not shown) coupled through a suitable reductiongear train (not shown) to a gear 64 fixedly secured to one end of shaft 53. The other end of shaft 53 is shown provided with a sprocket 6%, which is coupled by means of a chain 68 to a sprocket It fixedly mounted upon one of the shafts 39. Also fixedly secured to this shaft 36 and rotatable with sprocket '10 is a gear #2, which is in mesh engagement with a second gear 14 fixedly mounted upon the other shaft 3%. Similarly, a pair of meshed gears 76, ll are respectively mounted on the shafts 52 and 53, gear l6 rotating with sprocket 6'3 and driving gear ll. From the above it is apparent that the gears l2, 14, IE and l? rotate concurrently and are driven by gear 66.

In operation, the cardboards M, which are stacked in a substantially upright position in the rack 2, are moved transversely toward the slot ['8 after which each cardboard M drops through said slot between the rods 58 (when provided), thence between rollers 32, whereupon the cement 39 is applied thereby to both sides of the cardboard in adhesive strips 78 of predetermined width. The rollers 32 drive the cardboard i l downwardly to a position between rods and, as the cardboard approaches slot h"; in shelf is, it first engages the tissue paper ll resting thereupon and then, while it is passing through the slot, folds the same along both sides thereof. (See Fig. 3.)

The folded tissue paper f and cardboard i next pass through the compression rollers 48 and which seal the combination into a laminated or composite article 86, the tissue paper being adhesively secured to the cardboard only along the adhesive strips 38, shown in dotted outlines in Fig. 4.

It is to be noted that the tissue paper 31 is not secured to the cardboard between the intervals '58 and is thereby provided with a certain amount of looseness which adds to the attractiveness of the completed article. After passing through the compression rollers 53 and the composite article is then dropped into a receptacle (not shown). At a later step of manufacture the composite article so is severed into individual display cards 82, shown in Fig. 5. This is accomplished by cutting longitudinally the composite article midway along the adhesive strips l8 and transversely across the article in accordance with the length of display card 82 desired.

While this invention has been shown and described with reference to certain particular embodiments merely for the purpose of illustration, it is understood, of course, that various modifications may be made in the details of construction of the machine without departing from the scope of this invention, as defined in the appended claims.
